Arborists spend a lot of time rigging rope down, but sometimes it's necessary to lift a limb or load. With these block and tackle sets, you can generate a serious mechanical advantage in your favor. Some of our arborist block and tackle kits even contain a progress capture device in the system, so that the load won't slip even if you let go of the rope.
Essential components for a creating a 3:1 Z-Rig or 4:1 Piggy Back with progress capture on 1/2" line. Contains 2 x RockO Auto Lock Carabiners, 2 SMC Micro PMP Pulleys, and 2 Sterling RIT Bound Loop Prusiks.
Double pulley with integrated cam that provides immediate progress capture without the need of prusik loops. Stainless pins retain the rope when a rigged system is packed so that system can be pulled out and used immediately. Manufactured from high quality aluminum and anodized to help prevent corrosion. Ideal for all rescue applications where a small mechanical advantage system is being utilized. Up to 1/2” capacity. 34kN / 7,650lb breaking strength (18 kN / 4,050 lb for the becket).
Generate mechanical advantage with the Advance Tech HX pulley from SMC with built-in progress capture and quick release of the cam (even under tension). This compact system can be used in place of bulkier block and tackle sets due to the high strength of the SMC pulleys and Rock O carabiners. A great system for quick mechanical advantage with built-in capture and smooth operation.
Contains: SMC Advance Tech pulley, 60' of 7/16" HTP rope, two Rock Exotica Rock O ORCA-locking carabiners, quick link, and SMC Advance Tech Mate Pulley. Color of rope may vary.
The Aztek Omni pulley incorporates Rock Exotica's burly swivel on a high-efficiency double-sheave block. The Aztek pulley set is the basis for the Aztek Elite system below, and are excellent for building mechanical advantage systems for rescue or pulling. The pulleys work best with the prusiks and rope included in the Aztek elite system, but are also available on their own for building your personalized mechanical advantage system.
Each pulley has a breaking strength of 8,092 lb (36 kN), a max rope diameter of 5/16” (8mm), and 1” sheaves (25mm). The Aztek pulley set weighs 15.4 oz.
The AZTEK elite system utilizes sewn cord products to create a mechanical advantage system. System contains two AZTEK Omni pulleys, 2 x 6mm sewn ratchets, and 2 Sterling SafeD carabiners. The AZTEK is contained in a compact hip-carry pouch. Creates either a 5:1 mechanical advantage or a 4:1 with a change of direction. Applications include lifting downed limbs, rescue, and more.
The Aztek Pro bag belts around the leg to put your Aztek kit easily at your fingertips and increase the user's ease of movement. This bag was modeled on tactical drop-leg rigs and is slim and compact, and buckles easily around the leg with a top strap which goes to the user's belt or harness. The components of the Aztek stack in the Pro Bag to keep the profile narrow. The pro bag has a zippered bottom for easy access to the edge restraint. In addition to the main compartment, the Pro Bag has an external pocket and Molle webbing which can be customized with carabiners, Malice clips, or other attachments.
Get more power for your work with this 4 pulley system. Upper block has integrated cam device to hold forward progress of rope. Can be used to help you get the most from your Port-a-Wrap. The mechanical advantage you generate with this set will help lift and lower the heaviest of loads. Replacement parts available.
Blocks have 1,000 lb WLL • Works with all 1/2” lines • Generates a 5:1 mechanical advantage.
Take the block and tackle kits above and add ArborMaster® Bigfoot rope pre-spliced (Sewn eye splice) to the upper block for a handy mechanical advantage system. Now available with longer rope sections for increased movement capacity in the load.
The Tree Pulling Kit is a set of components that can be put together to create a 3:1, 4:1 or 5:1 progress-capturing haul system. This kit is available with 150' of 1/2" HTP or as a hardware only option. Both kits include: RIT 9mm Eye to Eye, RIT 9mm Bound Loop Prusik, (2) Steel AL carabiners, (2) SR PMP2 pulleys, Rope Option (includes items listed above, plus):150' of 1/2 HTP, Rope bag.
This kit uses the fiddle blocks above with a Gibbs quick-release rope grab to provide serious lifting power with a secure progress capture. Generates a 5:1 advantage and comes with a built-in progress capturing rope grab. Allows 10-15’ of movement in the load.
Contains: 2 fiddle blocks, 50’ of Bigfoot rope, 2 screw locking carabiners, and 1 Gibbs rope grab.

(Sling and Port-a-Wrap sold separately)
This kit uses 2 CMI pulleys with a prusik for a more compact mechanical advantage set. Generates either a 4:1 or a 5:1 mechanical advantage, depending on how it is set up. Does not have a progress capture feature. Allows 10-15’ of movement in the load.
Contains: 2 double sheave pulleys, 50’ of Bigfoot rope, 2 screw locking carabiners, 1 screw link, and 1 length of prusik cord.
This kit uses 7'16" rope and compact pulleys to be a very portable mechanical advantage kit. Generates either a 4:1 or a 5:1 mechanical advantage, depending on how it is set up. Allows 5-8’ of movement in the load.
Contains: 2 double sheave micro pulleys, 25’ of Blaze rope, 2 screw locking carabiners, 1 screw link, and 1 length of prusik cord.
